MR. PRESIDENT,—I am to speak of the Duel between France and Germany, with its Lesson to Civilization. In calling the terrible war now waging a Duel, I might content myself with classical authority, Duellum being a well-known Latin word for War. The historian Livy makes a Roman declare that affairs are to be settled "by a pure and pious duel"; [Footnote: "Puro pioqne duello."—Historie, Lib. I. cap. 32.] the dramatist Plautus has a character in one of his plays who obtains great riches "by the duelling art," [Footnote: "Arte duellica."—Epidicus, Act. III. Sc. iv. 14.] meaning the art of war; and Horace, the exquisite master of language, hails the age of Augustus with the Temple of Janus closed and "free from duels," [Footnote: "Vacuum duellis."—Carmina, Lib, IV. xv. 8.] meaning at peace,—for then only was that famous temple shut.
